Monsanto Enviro-Chem Systems
Adsorbtion Towers engineered-to-order, instantly!
Enviro-Chem Systems, Inc., a wholly-owned subsidiary of Monsanto Company with 300 employees, designs and constructs plants for the sulfuric acid industry. The company offers clients complete, turnkey solutions built to their requirements or any part of a solution. A leader in its worldwide market, Enviro-Chem has designed plants and performed modernization projects for many long-term clients.
using AutoTower, a Design++® solution
Applying Company Knowledge Assets
The goal of the AutoTower project was to create a design system that automated as much of the design process as possible while freeing engineers to optimize design configurations. The key focus was to substantially reduce the number of engineering man-hours needed to design absorbing and drying towers.
The development team took the knowledge of their own human experts and applied it through computerized tools. This type of automation, called Knowledge-Based Engineering or KBE, applies knowledge and company standards, performs analysis to determine the configuration of the internal systems, then passes the data to build a 3D model of the tower and generate the 2D drawings.
Focus on Quality
The company prides itself on total quality in design, which is important because a typical plant costs more than $25 million.
Each plant is custom engineered and requires thousands of hours of engineering and design time. To distinguish itself in a highly competitive market, Enviro-Chem continually looks for innovative ways to improve quality, reduce engineering hours in its design process, and reduce design errors in the field.
Capturing the Expertise
Enviro-Chem, along with a Design Power VAR (value added reseller) Integration Partners, Inc. utilized Design++® to form the knowledge engine core of the AutoTower system. With Design++ the team was able to develop a system that captured the work process knowledge that is used in creating tower designs. Using a custom designed graphical user interface (GUI), engineers enter the design parameters for a tower design and AutoTower handles the rest.
Design++ was used to create a detailed data-centric model which represents the process of designing and engineering a tower. Based on input from designers, the model interacts with CAD, Oracle and an engineering analysis module to automatically configure a detailed tower design. As a result of this highly automated process, engineers and designers are free to optimize tower designs.
Powerful Results
The initial goal with the Design++ -based system was to automate up to 80% of tower design while still allowing the engineers some freedom for decision making and creativity. Design changes are easy and fast since the Intelligent Change Manager feature of Design++ automatically modifies components of a design that are affected by a change while non-affected components remain untouched. With AutoTower engineers are more effective because their time is focused on optimizing the configurations instead of executing repetitive CAD and/or analysis operations.
Enviro-Chem application developers have been trained in the development of Design++ -based applications. This has resulted in Enviro-Chem assuming full ownership of the application which allows timely modifications and enhancements to extend its capability to meet the evolving requirements of their enterprise.

Management Endorsement
Barbara Van Hee, Project Manager for AutoTower says,
"With Design++ we were able to create a system that is easy to use and produces the design results we need in a fraction of the time we have been accustomed to. We continue to add additional functionality to AutoTower and are evaluating other potential applications. This is truly powerful technology."
